A History of UNIX before Berkeley
From TUHS
This article traces some of the intermediate history of the UNIX Operating System, from the mid nineteen-seventies to the early eighties. It is slightly updated from an article that appeared as ``The Evolution of UNIX from 1974 to the Present, Part 1in Microsystems, November, 1984 (Vol 5, Number 11), page 44. It was intended as part 1 of 3; unfortunately that issue was also the last issue of Microsystems. This article discusses ``Research UNIX; v6, v7 and v8, and tells the tale of many programs and subsystems that are today part of 4BSD and/or System V.
